If there is short circuit in power supply, fuse will blow itself to disconnect the circuit just to avoid fire or further damage in unit. Please check power supply of your unit.

My sansui 1000 receiver keeps blowing fuses


Fuses blow when there's an overload. This is often caused by the main power amp devices located on the heat sink. If they are transistors you can test them with an ohm meter. It will be just like you have put the two test probes together on the separate pins of the device.

My teac ag-680 fuse keep blowing everytime i replace it and plug the reciever up


are short in the audio output transistors may have been short since a channel 2 or maybe 4, also open resistance check carefully and change them after you put a 75w bulb in series 100w or where is the fuse clearly, you have to remove the fuse when you put the focus if all is well will turn on only a small incandescent and amplifier work well you put audio speakers and there will, if everything is well put the fuse back and ready.

Every time I switch on the receiver it blows a fuse. There is obviously a short somewhere but I have no idea where. Any general problem areas with this receiver?


Sounds like its time to get it repaired.

If the fuse keeps blowing and you replace it and it blows - its telling you there is a problem.

HAve you checked the fuses are exactly the same - is it slow blow? Is it the correct ampereage?

If the fuse is not exactly correct then get some for a final test.

If you've alreqady done this get it to the repair shop before the fuse blows too slowly and some serious damage is done.

GOOD LUCK

Goodmans GDVDR319 Was unplugged recently & whn plugged back in wouldn't come back on. Each time a new fuse has been put in the plug. In the past when it has been unplugged it has taken between...


You don't say if it's blowing the fuses.

If it is, it's dangerous to keep turning it on until you have someone resolve the problem.

If it comes back on after a few days of idleness the fuse isn't blowing as they rarely self-heal.

Have you tried another power cord?

Keeps blowing fuses interanlly, any ideas why


Hello, the problem of the continuos blowing of fuse internally is as a result of a defected component on the pcb board of the recevier . you can do this by removing the cover of the recevier and check for the power transistor , power capacitor, if is defected with the use of a multimeter, replace for a new one of the same number

Keeps blowing fuse.


Dissconnect ALL speakers from back of unit then try to turn on.
If it works you have a speaker short.
If not, you have a more serious problem.
DO NOT replace the fuse with anything else but what was specified, as it can cause a fire!

When a receiver does this, it is know as the "protect mode". This keeps the receiver from causing more damage to the components in it, by shutting it off when it detects an abnormal amount of voltage or current.

If you had to replace the fuses, it is most likely that you have a blown channel in the receiver.

You put 8 amp fuses in, so I hope that the fuses that blew were 8 amps as well. If you put fuses in that are higher rated in amps than the ones that blew, you will most likely cause more damage to the unit than need be. If the fuses keep blowing, please stop putting new fuses in again until the unit is repaired. Every time a fuse blows, it is because of too much current is going thru the unit. Having too much current is a very bad thing for electronics, it causes components to short out and sometimes even catch fire if the fuse is higher rated than it is supposed to be.

To find out just what parts will need to be replaced, you need a multimeter and then you will need soldering tools to remove the bad parts and put the new ones in.

When an amplifier channel gets blown, there are normally around 5 to 10 parts that will need to be replaced. If you do not replace every single bad part in the channel that has blown, you will most times blow up all the new parts that you just put in.

If you have no experience with electronics, you really should take it in to a service center for repair. If you are willing to try it yourself, let me know and I will guide you thru the troubleshooting steps to help you identify all the faulty components.

Onkyo is very well made equipment and is worth getting fixed.

A blown channel can normally be repaired for around $100 to $150, just depending on the shops rates and the extent of the damage.

Let me know if you need more help.

Fuse keep blowing off


If the fuse keeps blowing, that is an indication that something has failed and is drawing too much current. Most likely it could be a problem with the power supply, such as a shorted rectifier diode or voltage regulator. Another possibility could be a shorted audio output module. Unfortunately, you'll have to take it to a repair center to be serviced.

Please let me know if I can help you further.

Good luck!

Teac ag-d9320 5.1 receiver fuse


Make sure the fuse you put in matches the power requirement of the device you're installing the fuse into, putting a fuse that does not handle the current will cause this, but do not overshoot as this may fry your device - it must match. If you know it's matched, then the device you're installing the fuse into may be faulty in such a way that it is drawing the wrong amount of power. This can be due to the power supply on the unit.
